Salient Features of Chandil Dam
Chandil Dam is a major component of the Subernarekha Multipurpose Project, constructed across the Subernarekha River. According to tradition, gold was once mined near the river’s origin at a village called Piska, near Ranchi. This is why the river is named Subarnarekha, meaning “streak of gold.” Even today, traces of gold particles can be found in its sandy beds. Below are some key facts and features of Chandil Dam:
